Physical Science- Celestial sphere, eliptical and eclipses

Celestial sphere

the backdrop that everything appears in the day or night sky

The observer always stands

in the middle of their celestial sphere

Horizon

edge or rim of hemisphere

Zenith

point that is directly overhead

Altitude

height above the horizon measured in degrees

Zenith

always 90 degrees

Horizon

always 0 degrees

Azmith direction

distance around the horizon from the north pole measured in degrees

Ecliptic

imaginary line around the planet, stretching from aries to libra

Perigee

moon is closer to earth

Apogee

farther to earth

For the celestial sphere the direction of North has an azimuth angle of how many degrees?

0 or 360 degrees

For the celestial sphere the direction of West has an azimuth angle of how many degrees?

270 degrees

If the place of the moon’s orbit about the earth where in the same plane as the Earth’s orbit around the sun, Solar eclipses would occur

every new moon

A lunar eclipse can occur during what phase of the moon?

full moon

For the celestial sphere the horizon is at an angle of how many degrees above the horizon?

90 degrees

The ecliptic

is a line on the celestial sphere that the sun roughly follows from sunrise to sunset

On the celestial sphere the altitude has a range between

0 and 90 degrees

For the celestial sphere the zenith is at an angle of how many degrees above the horizon?

90 degrees

If the plane of the moon’s orbit about the earth where in the same plane as the earth’s orbit around the sun. Lunar eclipses would occur…

every month

A solar eclipse occurs during what phase of the moon?

new moon
